Answer:

E

Step-by-step explanation:

The problem with choices A B C D is that the molecular balance numbers are incorrect. E is the only one correctly balanced. For example in A is balanced as

3Mg + 2H2O ===> 3Mg0 + 2H2

The Mg's are correctly balanced.

So are the hydrogens. But take a look at the 0xygens. There are 2 on the left and 3 on the right. The equation is not balanced correctly. B and C have the same problem. One of elements is not balanced correctly.
